> * AbstractFileSystem.checkPath looks suspiciously like it's path validation just checks host, not authority. That needs a test too.
> * And we should cut the @LimitedPrivate(HDFS, Mapreduce) from Path.makeQualified. If MR needs it, it should be considered open to all apps using the Hadoop APIs. Until I looked at the code I thought it was...
